A researcher claims that the Makira Island and the Santa Ana Island flycatchers are diverging into different species. Identify T

WO potential prezygotic barriers that may be contributing to the divergence and speciation of these two populations of birds. Identify ONE piece of evidence that would indicate that speciation has already occurred within the flycatcher populations.

Answer:

Prezygotic barriers:

1. Habitat isolation

2. Behavioral isolation

Explanation:

Pre-zygotic barriers are the barriers which do not allow the formation of the zygote in the organisms.

The two mechanisms of the pre-zygotic barriers are the:

1. Habitat isolation: the Flycatchers do not share the same habitat which is also mentioned in the question that they live on different islands.

2. The behavioural isolation: the Flycatchers could have evolved the different mating rituals as a result of which the could not interbreed.

Thus, Habitat isolation and Behavioral isolation are correct.

What problems do desert plants and rainforest plants have in regards to water and how have they adapted to deal with these probl
Juli2301 [7.4K]

The desert plants ans the rainforest plants both have problems with water, just that they are total opposite ones. The desert plants have problems because they do not have enough water. In order to cope with that, these plants have developed methods through which they are able to retain water and not a single drop to evaporate from them. They also are able to take in water from the air, and have enormous root systems. The plants in the rainforests have problems with too much water, so they have adapted very wide leaves so that the water doesn't go toward their roots. The roots also are able to restrict the intake of water, while the plants themselves have extremely high tolerance to water. They also have developed larger pores on their leaves in order for the water to evaporate more easily from them.

Protein recommendations is the amount of daily required dietary proteins for a person base in its weight.

Christie's Doctor recommend 40grams of dietary protein and she has already consumed 50% of it. This meant that she has consumed about 20 grams of the required dietary protein and she needed additional protein source to complete her daily requirements. Therefore, Christie needs additional four servings of snacks to meet her daily protein recommendations.

tensa zangetsu [6.8K]

Answer:

The correct answer would be - nitrficiation, denitrification, nitrogen fixation, and decomposition.

Explanation:

Thiobacillus denitrification is a facultative, obligate chemolithoautotrophic anaerobic bacterium that is well known for its ability to couple the oxidation of inorganic sulfur-based compounds to denitrification.

The name of the bacterium is derived from its function or the metabolic ability as it performs denitrification on thio (sulfur) based inorganic compounds by the process of oxidation. This process helps in bioremediate groundwater by these processes of nitrogen fixation by oxidation of inorganic compounds of sulfur.

Thus, the correct answer is - nitrification, denitrification, nitrogen fixation, and decomposition.
